Title: Graphing Periodic Properties



Title: Graphing Periodic Properties

Purpose;

To demonstrate periodic properties of elements

To practice graphing

To determine relationship of atomic number and properties via analysis of graphs

Materials

Periodic Table

Periodic Properties Chart



Online Graphing Site: or

Procedure:

1. Construct graphs for the first 54 elements using the following properties.

a. atomic number vs atomic mass

b. atomic number vs boiling point

c. atomic numbers vs atomic radius

d. atomic number vs melting point

e. atomic number vs density

f. atomic number vs first ionization energy

2. Work in groups of 2, each of you constructing 3 graphs.

3. Cut-and-Paste the graphs in the results section.

4. Determine the relationship demonstrated by each graph.

Determine the elements that are on peaks and valleys of charts demonstrating a periodic relation.

(direct, indirect, random, regular periodic, irregular periodic, etc)

5. Determine the slope of any graph that displays a direct relationship.

Results: The Graphs

Discussion:

1. Comment on the properties that demonstrate a direct relationship.

2. Comment on the properties that demonstrate a random relation.

3. Comment on the elements that are at the PEAKS and VALLEYS in the graphs that show a periodic relation.

Conclusion: not necessary!

Reflection: personal statement about what you learned from the activity.

Extension: Define the following terms: melting point, boiling point, atomic radius, ionic radius
